Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery to ensure safety while working on the engine.
Raise the vehicle using a jack and secure it on jack stands if necessary.

2. Inspect Engine Oil

Remove the oil dipstick and check the oil level; add oil if low.
If oil appears dirty, drain the old oil using a wrench and an oil pan.
Replace the oil filter with a new one before refilling with manufacturer-recommended oil.

3. Inspect Valve Train Components

Remove the engine cover using a socket set.
Visually inspect the rocker arms and lifters for excessive wear.
Replace any damaged components with OEM parts.

4. Check Timing Chain/Belt

Remove any covers obstructing access to the timing chain/belt.
Inspect for wear and ensure proper tension; replace if necessary.
Reinstall covers securely with appropriate torque specifications.

5. Replace Faulty Components

If diagnostic steps indicate faulty fuel injectors or ignition coils, replace them.
Use a socket set to remove and replace the components, ensuring proper connections.
